A natural gas processing complex in Butler County will see another expansion to handle growing production from the Marcellus and Upper Devonian shale formations, MarkWest Energy Partners said recently.
The Denver-based midstream company said the expansion of the Keystone complex in Evans City is backed by new agreements with Rex Energy, a driller based in State College, and EdgeMarc Energy, a driller based in Canonsburg.
MarkWest plans to build Bluestone III and Bluestone IV, both of which are 200 million cubic feet per day (MMcf/d) plants that are expected to begin operations in late 2015 and early 2016, respectively.
In addition, MarkWest will build 40,000 barrels per day (b/d) of additional de-ethanization capacity and more than 20,000 b/d of additional propane and heavier natural gas liquid fractionation capacity, the company said.
Rex Energy recently expanded its footprint in the region with the acquisition of about 208,000 acres from SWEPI, LP, an affiliate of Royal Dutch Shell for $120 million in cash.
